Clario
For AI-first teams

Clario, right inside your editor.

The same humanize and authenticity engine that powers the app is also a Model Context Protocol server. Point Claude Code, Cursor, or any MCP client at it, and your agent can score and re-voice copy without leaving the terminal.

authenticity_score { text, voice? }

Scores any text 0 to 100 for how human it reads, with the AI tells flagged span by span. Optional voice to check against.

humanize { text, voice? }

Rewrites text so it reads human and, if you pass a voice, sounds like that brand. Returns the rewrite plus what changed.

Add to your MCP client 
{
  "mcpServers": {
    "clario": {
      "command": "bun",
      "args": ["run", "/path/to/clario/mcp/index.ts"],
      "env": { "DEEPSEEK_API_KEY": "sk-your-key" }
    }
  }
}
  1. Clone the repo and set your DeepSeek key in the config above.
  2. Drop the snippet into your MCP client settings (Claude Code, Cursor, and others).
  3. Ask your agent to "score this for AI slop" or "humanize this in our brand voice."

Source lives in mcp/ in the repo. It reuses the exact prompt builders behind the web app, so the terminal and the browser give the same result.
